A. F. HUTCHINSON HANGER FOR SCREW CONVEYERS Filed Feb. 2, 1935 Patented Nov. 19, 1935 unrrso STATES PATENT OFFICE 4 Claims.

This invention relates to hangers and more particularly to hangers for use with conveyers especially adapted for the conveying of cotton or the like.

An object of this invention is to provide a hanger for a conveyer such as a conveyer used in the movement of loose cotton which is so constructed that the hanger will not act as a means to clog the trough in which the cotton is moving as is the case with hangers at present in use.

Another object of this invention is to provide a hanger of this type which is of simple construction and may be readily mounted on troughs at present in use for rotatably supporting the conveyer shaft and the conveyer within the trough.

The above and various other objects and advantages of this invention will in part be described and in part be understood from the the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing wherein:--

Figure 1 is a detail side elevation partly broken away and in section of a hanger constructed according to an embodiment of this invention 1 showing the hanger in applied position on a trough, the trough and the conveyer within the trough being shown in dotted lines.

Figure 2 is a detail end elevation of the hanger.

Referring to the drawing wherein like characters of reference designate corresponding parts throughout the views, the letter T designates generally a trough through which loose cotton or the like is being conveyed and the letter C designates generally a conveyer of the screw type which is secured to a shaft S and which is rotatably supported within the trough T. This conveyer C preferably turns in the direction shown by the arrow in Figure 1.

In present constructions the shaft S is supported by a hanger which extends straight across the top of the trough T but in practice it has been found that this type of hanger is impractical due to the fact that one side of the hanger at the top of the-trough has a tendency to cause a clogging of the cotton or other loose material. In order, therefore, to provide a suitable hanger which will rotatably support the shaft S of the conveyer C within the trough T, I have provided a hanger comprising a vertically disposed arm I 8 which is provided at the upper end thereof with a substantially right angularly disposed arm II secured as by bolts, screws or other fasteningdevices I3 to one side of the trough T at the'top thereof.

An arcuate arm I2 is integral with thedependent arm III and extends oppositely from the straight horizontally disposed arm II and is pro- ,5:

'vided at its free end thereof with a lug I4 having suitable holes through which fastening devices I5 or the like may extend for securing the arm I2 to the top of the opposite side of the trough T. The vertically disposed dependent arm I0 is provided at the lower end thereof with one-half portion of a bearing I6 and another half portion ll of the bearing for the shaft S engages the integral bearing portion I6, Preferably the bearing I6 includes an inner shell I8 which may be formed of babbitt or the like. The removable bearing member I! has a channel I9 in substantially the central portion thereof and a U-shaped bolt generally designated as has 20 the bight thereof engaging within the channel I9. The belt 20 has one short leg 2| thereof extending along one side of the dependent arm I0 and this short leg extends through the inner end of the horizontal arm II and extends thereabove. A nut 22 engages the threaded upper end of the short leg 2|. The other or longitudinal leg 23 of the U-bolt 20 extends on the opposite side of the dependent arm I0 and is adjustably secured as by a nut 24. The curved arm I2 extends above the top of the trough T for a suitable distance so that when the conveyer C is in operation and is rotating in the direction shown by the arrow in Figure 1, the cotton which is carried over the top of the conveyer C will not 3 contact with the supporting arm I2 as it moves longitudinally of the trough T and also transversely of the trough.

In the use of the hanger structure hereinbefore described, the laterally extending arms II and I2 are secured as by fastening means I3 and I5 to the upper ends of the trough T with the dependent arm I0 extending substantially downwardly through the center of the trough T in a position where the conveyer C will be rotatably supported adjacent the bottom of the trough T. Through the use of the U-bolt 20, the bearing including the two parts It and I"! may be adjusted so as to take up any wear caused by the shaft S or may be suitably replaced through the use of a replacement member similar to IT. The bearing I6 is lubricated by means of an oil channel 25 extending vertically through the dependent member I0.

What is claimed is:

1. A hanger as set forth, comprising a pair of opposed arms, one of said arms being relatively straight and the other longitudinally curved, a dependent bearing supporting member integral with said arms and extending downwardly from the junction of said arms, and a bearing on the lower end of said member.

2. A hanger as set forth, comprising a straight arm, an upwardly curved arm opposed to said straight arm and integral therewith, said curved arm having the free end thereof terminating in a plane substantially coplanar with the lower side of said straight arm, a dependent bearing supporting member integral with each of said arms and extending downwardly from the junction of said arms, and a bearing at the lower end of said member.

3. A hanger as set forth, comprising a substantially straight arm, a longitudinally and upwardly curved arm integral with said straight arm and opposed thereto, said curved arm having the free end thereof terminating in a plane substantially coplanar with the lower surface of said straight arm, a dependent bearing supporting member integral with each of said arms and extending downwardly from the junction thereof, a bearing member secured to the lower end of said supporting member, said bearing member including one portion integral with said supporting member and another portion detachable from 5 said first portion, and means for securing said detachable portion to said first portion.

4. A hanger as set forth, comprising a substantially straight arm, a longitudinally and upwardly curved arm integral with said straight arm and opposed thereto, a dependent bearing supporting member integral with each of said arms and extending downwardly from the junction thereof,,a bearing at the lower end of said supporting member, said bearing including one portion integral with the supporting member and another portion detachable from said first portion, a U-shaped bearing securing member engaging said detachable bearing portion and extending on opposite sides of said supporting member, said U-shaped bearing securing member having the free ends thereof extending through each of said arms, and means threadably securing the bearing securing member to said arms.
